The mouse homolog, parp3, has been associated with cell cycle progression through DNA break repair and histone modification.76Lnc-parp3 was also distal to caveolin 3 (cav3), a component of myocyte caveolae involved in natriuretic peptide signaling and cardiac hypertrophy in a mouse overexpression model,77 but cav3 was not differentially expressed. Here, CAV3 is linked to cardiac hypertrophy.
